MICRO PLATE HEAT EXCHANGERS


Heat pump technology answers modern society’s urgent need for efficient, environmentally friendly heating systems. And as our efforts to save energy intensify, the demand for heat pumps just keeps on growing.

This situation means new challenges for heat pump manufacturers. Competition is fiercer than ever, raw material prices fluctuate, customers want lighter, slimmer products, and increasingly strict environmental legislation drives the need to reduce the refrigerant charge.

Now, Danfoss brings you a heat exchanger concept that addresses all these needs, starting with heat transfer itself. Find out how we can help you develop tomorrow’s heat pumps, to keep your customers comfortable and your business competi-tive in the future.

The price of stainless steel has risen steeply over the last three years and this trend is predicted to continue. This has a dramatic

effect on heat pump production costs.

35%Lower hold-up volumeEnables significant reduction in refrigerant charge


To help our customers meet the challenges of today’s heat pump business, Danfoss introduces the innovative Micro Plate Heat Exchanger (MPHE) with its revolutionary plate design.

New plate design

In place of the traditional BPHE herringbone pattern, our new MPHEs have an indented surface. This apparently minor change leads to a major improvement in heat transfer. And as we shall see, it enables a series of other important efficiency gains, which result in significant and steady savings for you. How is this possible? Resource efficiency

For a start, MPHEs can be made smaller and more compact. This means they use less raw material, which not only low-ers initial costs but also makes your business less sensitive to raw material price fluctuations. Secondly, MPHEs require a smaller refrigerant charge. Besides the obvious environmental benefits, this cuts costs and, once again, reduces sensitivity to changes in price.

Steady savings in an unpredictable world

By minimising the use of raw materials and refrigerants, while maximising efficiency, our MPHEs save you money right away and, at the same time, they protect your business from the worst effects of future price rises. For these and many other reasons, using Danfoss MPHEs in your air and ground source heat pump applications helps to stabilize your business and facilitates the development of more efficient and environmentally friendly heat pump systems.

SMARTER HEAT TRANSFER WITH MPHEs


To find out exactly how much you can save by using MPHEs instead of BPHEs, we took a closer look at one sample product: a ground source heat pump with 60 kW heating capacity using R410A refrigerant, standard B0/W35 °C temperatures, and a pressure loss of 20 kPa. Starting with a BPHE and an MPHE with the same purchase prices, we examined how raw material price rises between 2010 and 2011 affected the manufacturer’s costs. Our calculations were based on the assumption that heat exchangers were purchased continually.

Impact on manufacturing costs

With raw material prices rising fast, how would the raw material surcharge affect you as a manufacturer during this period? We discovered that by buying our compact, lightweight MPHEs instead of BPHEs, you could have saved €65.40 per heat pump.

But that’s not all. Reducing refrigerant hold-up volumes by 35% also greatly reduces the cost of filling your heat exchanger with refrigerant. Using MPHEs instead of BPHEs you would save €58 per unit, based on current prices. In the future, refriger-ant prices may have an even greater impact on your total costs, and the savings potential may be even greater.

Today, the total cost advantage of using MPHEs instead of BPHEs adds up to an astonishing €123 per unit! This calculation does not take carbon and other environmental taxes into account, so, in reality, your savings could be even higher. We recommend that you investigate the environmental taxes in the countries where you do business and factor these into your own calculations.

See how costs are reduced by using the new MPHE technology instead of traditional BPHEs in your heat pumps. We made a direct comparison and here are the results.

€65.40 plus €58.00 means a total saving per heat pump of €123.40.

35% lower hold-up volume reduces purchase costs and gives greater price stability so you save €58.00.

40% lower weight reduces purchase costs and gives greater price stability so you save €65.40.


Compared with a traditional BPHE, with its three-dimensional flow, the innovative MPHE has a two-dimensional flow with a more uniform velocity which enhances heat transfer.

How often do you see a quantum leap in industrial design? It’s certainly not every day. In the world of heat exchangers, it’s not even every decade. The same basic heat exchanger model has been in use since the 1970s.

Now, thanks to Danfoss’ revolutionary MPHE, things are changing fast. The new channel geometry of our MPHEs improves the flow across the plate and the utilization of the surface area, leading to a more uniform flow velocity. This enhances heat transfer and enables greater efficiency in heat pump applications with a narrow temperature approach.

Enhanced heat transfer combined with a highly resource-efficient design (economical use of raw materials and low refrigerant charge) makes our MPHE technology an excellent route to improved heat pump performance and lower environmental impact.


In close-up, we can see how the MPHE design gives a more uniform channel velocity. Additionally, the plates have a broad, flat brazing area compared with BPHEs, which reduces stress and gives you a more robust heat exchanger.

New channel plate pattern – verified technology.


PUT IT ALL TOGETHER, AND WHAT DO YOU GET?

Our new MPHEs are 40% lighter than traditional BPHEs. However, thanks to their innovative design and broad flat brazing surfaces, this weight reduction has been achieved without compromising on strength.

LIGHTWEIGHT BUT STRONG

The MPHE channel plate pattern allows greater flexibility in application design. Varying the number, size and placement of indentations enables MPHEs to be fine-tuned to provide optimal heat transfer and minimal pressure loss in all kinds of heat pump applications.

PLATE DESIGN FREEDOM

WELL-KNOWN PRODUCTION METHODS

The enhanced heat transfer of our H-range MPHEs leads to an increase in efficiency in your heat pump systems, which in turn leads to a reduction in energy consumption and accompanying cost savings. And of course, the more efficient your heat pumps are, the more attractive they will be to your customers.

MPHEs have a small hold-up volume, which means cost savings, better price stability and a greener product profile. Further-more, the minimal use of refrigerants reduces the need for F-gas inspections and in some cases eliminates it completely.

REDUCED HOLD-UP VOLUMES

Compared with herringbone BPHEs, MPHEs have a 40% lower CO2 footprint. This is in part due to the efficient use of raw materi-als in their construction, but also to the lower refrigerant charge.

SMALLER CARBON FOOTPRINT

Since MPHEs transfer heat more efficiently, a more compact model gives you the same performance compared with other technologies. The result is better utilization of raw materials, which reduces costs and improves price stability over time.

IMPROVED UTILIZATION OF RAW MATERIALS

The new MPHEs are based on proven technology and manufactured using reliable, well-known production methods.


SO MANY SAVINGS

MPHEs are designed to deliver the best possible performance using the minimum of resources. The result is a series of improvements which give you both immediate and long-term savings.
